Bill suddenly double

[chungtd]

Hello,

I just got the email with the bill for January 2016. It was in more than double comparing to other months.

I am using SMART Net 1000 for 2 years. The bill is around 13-15 EUR per month.

This month, it became more than 30 EUR for no-reason.

Could you tell me why?

P/s. I tried to call Hotline service but they weren't able to speak English! Too bad for a big company like T-Mobile. 

I am wanting to terminate contract with T-Mobile and use another service provider.

Hello DucChung,

Is it possible, that we charged the yearly "Basispaket" on this bill?

It costs EUR 20,00 once per year.

We would be sorry, if you terminate your contract with us, because we are glad to have you as one of our customers.

Best wishes,

Andrea
